Title: Device for previously detecting tape end
Inventor: ISHII TAKATOSHI
IPC: G11B15/61
Filed: 1988-09-28
Abstract: PURPOSE:To easily detect the end of a tape beforehand by detecting the tape or a feed reel with the output level of a light receiving device which detects reflected light from the tape or feed reel irradiated with the light of a light emitting device. CONSTITUTION:When a standard tape 1 for adjustment is wound around a feed reel 3 in a large quantity, the light emitted from a projector 4 is reflected by the tape 1 after passing through a transparent window 2 and enters a light receiving device 5 which outputs a voltage based on the quantity of the reflected light. The detecting distance between the light receiving device 5 to the tape 1 is designated as A. As the tape 1 is wound around a take-up reel 9, the tape 1 on the feed reel side becomes less and no tape exists at a previously detecting position. Then the light reflected by the tape 1 so far advances to the reel 3 and made incident on the light receiving device 5 after the light is reflected by the reel 3. Therefore, the detecting distance changes from the A to B and, accordingly, the quantity of the light entering the light receiving device 5 also changes. The reel 3 can be detected when the input voltage becomes higher than the threshold level by comparing the input voltage with a threshold.

Title: Magnetic recording and reproducing device
Inventor: OKUDA MAKOTO
IPC: G11B25/06
Filed: 1988-09-27
Abstract: PURPOSE:To always attain stable tape traveling by slightly inclining the rotational center axis of rotary magnetic heads from a magnetic tape guide face. CONSTITUTION:This device is constituted of a guide plate 24 for a magnetic tape 20 having a recessed groove whose width is gradually changed and a scanner part in which the rotational center axis 29 of rotary magnetic heads 28a to 28d is slightly inclined from the guide face of the magnetic tape 20.

Filed: 1983-12-21
Abstract: PURPOSE:To enable a highly accurate measurement of noise with a handy circuit by a method wherein a sine wave signal amplitude modulated by a window function is inserted into a measuring portion in a composite video signal to make a measuring video signal. CONSTITUTION:A signal sine wave signal from a sine wave oscillator 19 is modulated with a modulator 21 by a window function from a window function generator 18 of a measuring signal source 17 is added with an adder 22 to a measuring portion of a composite video signal containing a synchronous signal from a test signal generator 18. Output of the adder 22 is fed to an equipment 12 to be measured, whose output is fed to a level measuring device 13, a gate circuit 23 and a synchronization circuit 15 and the level of noise outputted from the circuit 23 is measured with a level meter 16. With the insertion of the sine wave signal thus amplitude modulated into the measuring portion, the expanse of a spectrum will not increase free from extraction of the modulated output inserted portion in the output of the equipment being measured of a video signal cycle. Thus, sine wave components are removed with a handy filter circuit thereby enabling an accurate measurement of noise while an equipment containing an A/D converter can be measured as well.

Title: Connector
Inventor: TSUJI KENJI
IPC: H01R13/58
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To improve assembling workability of electric cables to a cover. SOLUTION: When each cable 4 is pierced through each cable piercing hole 20, retaining pieces 22 abut on an outer circumference of the cable 4 with them displaced to the piercing direction of the cable 4 and bent to enlarge a diameter of the cable piercing hole 20. When a pulling force to the opposite direction of the displacement direction of the retaining pieces 22 is applied to this cable 4, the retaining pieces 22 are returned to the pulling direction and displaced such that their inner circumferential edges bite into the outer circumference of the cable 4. When this biting reaches a limit, the returning action of the retaining pieces 22 and the movement of the cable 4 to the pulling direction stop. Thereby, application of the pulling force to an engaging part of a terminal metal fitting and a lance is prevented.  Because assembling work of the cable 4 to a cover 2 is easily completed by only piercing the cable 4 through the cable piercing hole 20, the assembling workability is improved.
